I'm so sad I feel like my son barley want to breastfeed and he's only been in daycare for a day :-( he won't breastfeed as often when I'm home with him like this morning our schedule was way off I can only pump like three times at school and I feel the will drastically drop my milk as I feed my son on demand and he eat way more then the three times I'd be pumping 😢😥😮💔
